Description

Technical field:

[0001] The present invention relates to the drug tiotropium bromide spray for the treatment of respiratory diseases, especially asthma, chronic obstructive pneumonia, bronchitis, etc., wherein the inhalable surfactant can be adjusted by adjusting the drug combination of tiotropium bromide aerosol without propellant The surface tension of the material makes the spray particle size, spray time and spray speed of the composition more suitable. Background technique:

[0002] Asthma is a chronic airway inflammation characterized by reversible airway obstruction and increased airway responsiveness. Airway obstruction is caused by two factors: increased secretions caused by bronchial mucosal inflammation, mucosal edema, and smooth muscle spasm stimulated by inflammation; while asthma Increased airway reactivity is also a result of damage to the bronchial epithelium due to airway inflammation. It is recognized that only by controlling the inflammation of the airway...
